Grain size (or particle size) is the diameter of individual grains of sediment, or the lithified particles in clastic rocks.
A granular material is a conglomeration of discrete solid, macroscopic particles characterized by a loss of energy whenever the particles interact (the most common example would be friction when grains collide).
Haloclasty is a type of physical weathering caused by the growth of salt crystals.
The International Organization for Standardization (ISO) is an international standard-setting body composed of representatives from various national standards organizations.
The term landslide or, less frequently, landslip, refers to several forms of mass wasting that include a wide range of ground movements, such as rockfalls, deep-seated slope failures, mudflows and debris flows.
In materials science, liquefaction is a process that generates a liquid from a solid or a gas or that generates a non-liquid phase which behaves in accordance with fluid dynamics.
Loess (from German Löss) is a clastic, predominantly silt-sized sediment that is formed by the accumulation of wind-blown dust.
A mineral is a naturally occurring chemical compound, usually of crystalline form and not produced by life processes.
